Description

Technical Field

[0001] This utility model relates to the field of door and window technology, specifically to a fireproof aluminum alloy door and window. Background Technology

[0002] There are two types of aluminum alloy doors and windows: ordinary aluminum alloy doors and windows and thermally broken aluminum alloy doors and windows. Aluminum alloy doors and windows are beautiful, airtight, and strong, and are widely used in the construction industry. In home decoration, aluminum alloy doors and windows are often used to enclose balconies.

[0003] The existing patent with authorization announcement number CN202954671U provides aluminum alloy doors and windows, including an aluminum alloy frame, a door leaf frame inside the aluminum alloy frame, and a drainage channel on the door leaf frame. The door leaf frame includes intersecting horizontal and vertical frames, and the aluminum alloy frame and both the horizontal and vertical frames have slots for installing the door leaf. This structure allows dust and rainwater to enter the slots in the frame along the door and window panel and be discharged from the drainage channel, thus maintaining cleanliness for a long time.

[0004] When the above-mentioned structure is in use, the aluminum alloy frame is prone to deformation after being burned by flames in the event of a fire, making it difficult to effectively isolate dense smoke and heat, thus shortening the escape time for people in the event of a fire. Therefore, it needs to be improved. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides a fireproof aluminum alloy door and window, comprising multiple frames 1, wherein the two ends of the frames 1 are inclined structures and are spliced ​​together.

[0026] The frame 1 has grooves 2 at both ends, and L-shaped reinforcing plates 3 are installed in the grooves 2;

[0027] The inner side of the frame 1 is provided with a mounting groove 5, and a fireproof sealing strip 6 is provided in the mounting groove 5;

[0028] The frame 1 has multiple cavities 4 inside, and heat insulation blocks are filled in the cavities 4. The shape of the heat insulation blocks matches the shape of the cavities 4, and the heat insulation blocks are inserted into the cavities 4.

[0029] In this embodiment, the L-shaped reinforcing plate 3 is bonded to the inside of the groove 2.

[0030] In this embodiment, the L-shaped reinforcing plate 3 is made of aluminum alloy.

[0031] Frame 1 splicing and reinforcement: Frame 1 is designed with beveled ends that are spliced ​​together. This beveled splicing method ensures a tighter connection between frames 1, allowing for more even force distribution when the door / window is under load, reducing stress concentration caused by improper connections. L-shaped reinforcing plates 3, made of aluminum alloy and bonded to the grooves 2 at both ends of frame 1, are installed within the grooves 2. Firstly, the shape of the L-shaped reinforcing plates matches the grooves 2, providing support and reinforcement to frame 1 from multiple angles when the door / window is subjected to impact or deformation, enhancing the strength of the connections and improving the overall structural stability. Secondly, the aluminum alloy L-shaped reinforcing plates 3 are made of the same material as frame 1, ensuring good compatibility and preventing deformation due to material differences under temperature variations, thus maintaining the connection effect.

[0032] In this embodiment, the surfaces of the frame 1 and the L-shaped reinforcing plate 3 are coated with a fire-retardant coating 7, which is an intumescent fire-retardant coating.

[0033] In this embodiment, the fireproof sealing strip 6 is a fireproof sealing rubber strip.

[0034] Fireproof and heat-insulating design: The frame 1 contains multiple cavities 4, each filled with a matching heat-insulating block. In the event of a fire, these independent cavities 4 first disperse heat, preventing the heat from concentrating and rapidly conducting in one spot. Instead, the heat is slowly transferred between the cavities 4, reducing the heat transfer speed within the frame. The heat-insulating blocks further block the heat transfer path; they are typically made of high-temperature resistant and heat-insulating materials, such as ceramic fiber. These heat-insulating blocks, filling the cavities 4, significantly reduce the impact of flame heat on the aluminum alloy frame, allowing the frame to maintain a relatively low temperature for extended periods, thus enhancing its resistance to deformation. Fire-resistant sealing strips installed in the mounting grooves 5 on the inner side of the frame 1 tightly seal the gaps between doors and windows when closed. In the event of a fire, these strips effectively prevent flames and smoke from penetrating the room through these gaps. Furthermore, under high temperatures, the fire-resistant sealing strips expand, further filling the gaps and enhancing fire resistance and smoke isolation. In addition, the intumescent fire-retardant coating applied to the surfaces of the frame 1 and the L-shaped reinforcing plate 3 also plays a crucial role. Once exposed to flames, the fire-retardant coating expands rapidly, forming a thick layer of heat-insulating foam. This acts like a protective armor for frame 1 and the reinforcing plate, effectively blocking heat transfer to the aluminum alloy material, reducing the frame temperature, and further ensuring the structural stability of frame 1.

[0035] The beveled joints at both ends of frame 1 and the inclusion of L-shaped reinforcing plates 3 significantly improve the overall structural strength of the doors and windows. In daily use, they can better withstand external forces such as wind pressure and impacts, are less prone to deformation and damage, and extend their service life. In strong winds, these structurally stable doors and windows can remain intact, preventing damage to indoor facilities due to window or door failure.

[0036] The combination of insulation blocks and a multi-cavity structure significantly reduces heat conduction. In summer, it effectively blocks outdoor heat from entering the room, reducing energy consumption of air conditioning and other cooling equipment; in winter, it prevents indoor heat loss, providing excellent insulation, reducing heating costs, and improving indoor comfort. For example, in buildings in cold regions, using these doors and windows can effectively reduce indoor-outdoor heat exchange and maintain indoor warmth.
